2. Fertilised by Laxtoris A Ipha (green; wrinkled; coats 

 transparent), two flowers gave 11 seeds exactly as above, 

 the purple being in this case clearly increased. 



In the following the purple sugar-pea was father. 



3. Laxtoris Alpha (green ; wrinkled ; coats transparent) 

 fertilised by the purple sugar-pea gave one pod of four 

 seeds with yellow cotyledons and round form. 



4. Fillbasket (green ; smooth but squared ; coats 

 green) fertilised by the purple sugar-pea gave one pod 

 with six seeds, yellow cotyledons * ; F'dlbasJcet size and 

 shape ; but the normally green coat yellowed near the hilum 

 by xenia. 



5. Express (" blue "-green cotyledons and transparent 

 skins ; round) fertilised with purple sugar-pea, gave one 

 pod with four seeds, yellow cotyledons, shape round, much 

 as in Fillbasket. 



6. British Queen (yellow cotyledons, wrinkled, white 

 coats) $ x purple sugar-pea gave two pods with seven seeds, 

 cotyledons yellow, coats tinged greenish (xenia ?), all round. 



So much for the "Purple" sugar-pea. 



I got similar results with Mange-tout Debarbieux. This 

 is a soft-podded Mange-tout or sugar-pea, with white flowers, 

 large, flattish, smooth seeds, scarcely dimpled ; yellow coty- 

 ledons. 



The colour is the peculiarly deep yellow of the "grey" mange- 

 tout.
